Telmisartan Versus Amlodipine in Patients With Mild-to-Moderate Hypertension

July 7, 2014 updated by: Boehringer Ingelheim

A Prospective Randomized Open-Label, Blinded-Endpoint (PROBE) Trial Comparing MICARDIS® (Telmisartan) (80 mg QD) and Amlodipine (5 mg QD) in Patients With Mild-to-Moderate Hypertension Using Ambulatory Blood Pressure Monitoring.

The primary aim of the trial is the effect of telmisartan versus amlodipine in lowering ambulatory diastolic and/or systolic blood pressures in the last six hours of the dosing interval in patients with mild-to-moderate hypertension as measured by ambulatory blood pressure monitoring (ABPM)

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

  • Night shift workers who routinely sleep during the daytime and whose work hours include midnight to 4:00 AM (ante meridian)
  • Patients receiving any investigational therapy within one month of signing the informed consent form. Note that patients who have participated in previous MICARDIS (telmisartan) studies may participate in this study provided there has been at least one month between discontinuing the previous study and signing the consent for the present study
  • Known hypersensitivity to any component of the formulations
  • Any clinical condition which, in the opinion of the investigator would not allow safe completion of the protocol and safe administration of trial medication

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Changes from baseline in diastolic and systolic blood pressure during the last six hours of a 24-hour dosing interval, measured by ambulatory blood pressure monitoring
Time Frame: Baseline (day 1), day 57 of the open-label period
Baseline (day 1), day 57 of the open-label period

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Changes from baseline in diastolic and systolic blood pressure during other times during the 24-hour ABPM profile
Time Frame: Baseline (day 1), up to day 57 of the open-label period
Baseline (day 1), up to day 57 of the open-label period
Changes from baseline in seated trough diastolic and systolic blood pressures as measured by manual cuff

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
